To create a graphghan you'll first need a pattern. Here is a practice graph to get you started. It's 15 stitches wide by 15 rows high. You can right-click to save it.
No matter what size graph you use, know that each square on the graph represents one stitch. To create this in single crochet you'll first want to chain the number of stitches in width on the graph + 1. In this case 15+1=16 chains. This foundation chain does not count as your first row.
|Chain 16 for the practice graph.|
|Sc in 2nd chain from hook & in each chain across.|
Chain 1 and turn. The ch-1 doesn't count as a stitch. It's just to raise your stitches up a row. For the second row and each remaining row you'll sc in each sc across following the color pattern on the graph. Chain 1, turn.
|Ch 1, turn. Following color pattern on graph, sc in each sc across the row.|
To change colors, insert the hook into your next stitch, yarn over and pull up a loop but don't finish the stitch yet.
|Insert hook into the next stitch, yarn over & pull up a loop.|
With your new color, leave a long tail (that you'll weave in later) and use the new color to yarn over and pull through the two loops on your hook to finish your stitch.
|Pull the new color through the two loops on the hook to finish the stitch.|
Now you have the new color on your hook and you can do the next stitch with the new color.
|Next stitch done with the new color|
Here's a little more of the graph done.
I hope that makes sense and helps. If you have any questions please feel free to comment. You can also send me a message on facebook. I've also recently started a facebook group for graphghans called KD Graphghans. There are several free and paid graph patterns there as well as more practice graphs. This is a place to learn and share. I've set it up as a closed group so that progress pictures can be shared without family and friends possibly seeing a gift in progress (unless they're also a member of the group). You just have to send a request to join. We'd love to have you! :) Kari
